Black pinstripe halter vest from the brand The Hilton Co. Might be part of a uniform. Does have some fraying on the shoulder as seen in photo and the back has a buckle but no holes in the strap which makes me believe there’s a missing piece. Could just tie it in the back instead. Has no tag size. In good, used condition
